I'm nearing the end of migrating all of our users and room calendars to Exchange Online. All of the users and calendars are on EXO and I have two exchange 2010 servers (1 CAS/HUB and 1 Mailbox server) left. I also installed an Exchange 2016 server with the mailbox role.

I'm trying to figure out my next steps to completely remove the 2010 servers while keeping the 2016 server for management purposes.

Do I just uninstall the last two 2010 servers and then run the hybrid configuration wizard on the 2016 server so that i can move new users to EXO?

Or do i need to run the hybrid wizard on O365 again?

At the end of the day all i need is the 2016 server to be able to change setting and move new users (i'm guessing i still have to add the user to the 2016 sever and then migrate to EXO). All email flow is going between O365 and an online service i use for spyware/viruses. My on prem server doesn't need to send or receive any mail, just manage users.

The vendor I was using to help me has kind of left me high and dry right now.
